Station: 13th St Br River: Animas County: San Juan WBID: COSJAF03A.
River Watch aims to generate high quality spatial and temporal water ecosystem data. In this document, you will find temporal graphs for all of the metals, nutrients, and field data for 103. Explore the data and make use of the in the top right corner of each graph.
River Watch analyzes water samples for 13 metals and cations, many of which occur naturally in trace amounts. The Water Quality Control Commission has set aquatic life standards for 9 of the metals analyzed by River Watch and sets a chronic and acute exposure level.
Most of the chronic and acute metal standards are calculated using a hardness dependent equation. The graphs below use the table value standards and field hardness to calculate the metals standards.
Note: Your station may have a site specific standard different to the table value standard shown in the graphs.
You can find the current table value standards here.
